EUGENE MEYER, OF NEW YORK N. Y.

RESONANCE noun Application filedAugust 14, 1922. Serial No. 581,762.

all w/wm it may concern Be it known that I, EUGENE MEYER, a citizen ofthe United States, and a resident of the borough of Manhattan, city,county, and State of New York, have invented certain new and usefulImprovements in Resonance Horns, of which the following is aspecificatime i My invention relates to horns used either for receivingor transmitting sound vibrations, and consists essentially in thecombination and incorporation, with such a horn, of one ormorapreferably a plurality, of

sound amplifying resonant tubes, substantially in the manner and for thepurposes herein fully set forth and described and claimed specifically.

In the. accompanying drawings I exempli'l y a practical embodiment ofthe essential features of my invention in conjunction with a conoidalhorn of well known configuration, and show a plurality of resonant tubespositioned internally and radially around the inner concavo conoidalsurface of said born, with the understanding that I do not limit myselfto this identical form and construction of parts, since modificationsmay be resorted to in arrangement, and in minor details, with likeresult, and without deviating from the spirit and intent of my inventionin this respect.

With this understanding,

Fig. 1, is a frontend elevation, of my improved resonance horn; I

Fig. 2, is a longitudinal section thereof taken upon plane of line 2-42,Fig. 1;

Fig. 3, is a diagrammatic representation of the inner surface of theborn, the latter being presumed to be split longitudinally and spreadout flat;

Fig, 4, is a diagrammatic elevation 'of the horn, howing its use as ameans of making sound records;

Fig; 5, is a similar view illustrating its use in conjunction withphonographic sound box;

Fig. 6, is a similar view showing the horn adapted for use as a trumpet;

Fig. 7, is a detail view of an elbow suitable for use'as a couplingbetween horn and phonograph sound box.

5; sound vibrations is Well known, and do not claim anything original inthis re spect, tue novelty in to present case can The function ofresonance tubes in ampliopen extremities toward the apex end h, of

the horn.

Thus in Figs. 1, 2, and 3 of the drawings I show a series of resonanttubes 1 1, representing. thirteen notes of the musical scale,

eight natural from E to E inclusive, and the five intermediate notes Di,Ct, Al Gt, and Ft, although I do not limit myself in this particular, asany number, and cornbination and arrangement of resonant tubes, may beresorted to in adapting-the device to various purposes and uses.

Preferably the series of resonanttubes r, 1-, are arranged radially asshown, and as related to the apex of the horn; and may be afixed to thelatter by glue, cement, or any other positive means.

S is a sound conveying tube or conduit, the main portion of which ispositioned in alignment with. the longitudinal axis of the horn, saidsound conduit S, being formed with a lateral extensions, protuberantthrough the side of the horn.

This sound conveying conduit S, is for the purpose of transmitting soundvibrations ineither directions. Thus, as shown in Fig. atpthe extraneousextension 8, thereof may be attached to a. record-producing device D, ofwell known construction, for making a record on the usual wax receivingdisc d; or the outer end of the extension 8, may be placed to the ear ofa person for the purpose of listening to sound vibrations received intothe mouth of the horn, and modified and amplified by the'resonator tubes1'1 01', a. phonographic sound box B, may be attached to the end of thehorn, as indicated in Fig. 5, to transmit the vibrations imparted by thephonogra hi'c record P, through the horn in intensifie volume, a tubularcoupling elbow e, such as indicated in Fig. 7, being used to connectthebox B, and the otherwise open apex end of the horn.

Or the apex of the vided with a mouth piece m, as indicated in Fig. '6,and the horn used as a speaking or singing trumpet if so desired. a facthorn H, may be pro I my sound amplifying horn may be adapted to many andvarious uses Without departing from the spirit and intent of myinvention. What I claim as my invention and desire to secure by LettersPatent is,

1. The combination with a conoiclal horn of the character designated, ofa plurality of resonant tubes, each for a definite note of the chromaticscale, positioned convergently therein, said tubes all having open endsfacing the producer from the inside of the horn, the other ends beingclosed, substantially in the manner and for the purpose set forth.

2. A conoidal horn of the character designated, having a plurality ofresonant tubes, each for a definite note of the chromatic scale, saidtubes being open at one end and closed at the other, and positioned inthe horn radially convergent thereto with their open extremities towardthe apex of the horn, substantially in the manner and for the purposeset forth.
